To @ZZ whom it muy concern:

Be it known that l, JULES MICHAUD, a cit-izen of France, residing at Paris, have invented new and useful Improvements in Rotary Printing-Machines, (for which l have obtained a patent in France, No. 169,880, dated June 5,1885, with certiiicate of addition dated February l2, 1886; also French Patent No. 178,606, dated September 18, 1886; Great Britain, No. 2,7 7 2, dated February 25, 1886, and No. 7,484., dated May 28,1887; Belgium, No. 72,096, dated February Q2, 1886 5 Germany, No. 893:60, dated April 1 1886, and Austria-Hun gary, No. 40,547, dated August 21, 1886,) of which the following is a specification.

My invention relates to rotary printing-machines which will permit of the printing, superposing, and folding of publications from two rolls of paper, or the printing and folding, without superposing, from one or two rolls of paper at will.

The invention is illustrated in the accompanying drawings, in which- Sheet 1 shows two. views of the `machine, Figure 1 being a section on line 3 4 of Fig. 3, and Fig. 2 a section on .line l 2 of Fig. 1. Fig.

mechanism being omitted. Figs. l and 5 are respectively a vertical section and plan view of the arrangement for the delivery of the sheets. Fig. 6 is a vertical section through the cutting and folding cylinders. Fig. 7 is a detail view of the arrangement of the counterpart or maiden in conjunction with which the cutting-knife works; and Fig. 8 is anend view of one of the folding-rolls, showing the operating-cams.

There are two series of cylinders-one on each side of the machine-and for each series an endless roll or web of paper is provided. The paper from the roll or reel V passes between the cylinders A and B, A being clothed with a suitable fabric or blanket and B carrying the printing-form, which may be of A metal type, electros, stereos, or zincos. The paper then passes between a second pair of cylinders, C and D', C being clothed with a suitable fabric or blanket and D carrying the form for printing the back or opposite side. In the same way the paper from the roll or reel V'2 is printed on its opposite sides between cylinders A2 and B2 for one side and between C2 and D2 for the back or opposite side, A2 and C2 being clothed with a suitable fabric or blanket and B2 and D2 carrying the forms. The paper from reel V, when printed, passes under roller e and over roller f and descends between the cutting and folding cylinders G H. The paper from reel V2, when printed, passes under roller t' and over rollers J f and descends between the same cutting and folding cylinders, G H as shown in dotted lines. The Webs from the two reels are thus superposed, their travel being such that the texts and the margins of the sheets coincide. The roller J, being adjustable, allows of the travel of the paper from reel V2 being lengthened or shortened, so that the superposition may be effected with great exactitude. The webs are then cut together and receive a first fold, and are carried by the cutter and folder G into a set of tapes, which conducts them above the rollers R for the second fold.

Fig. 6 on Sheet 8 shows the special construction of the cutting and folding cylinders.

Cylinder H carries the cutting-knife a, which is serrated-that is, it has parts of its cutting-edge opposite the threads, hereinafter described, cut away, so that it will not sever the paper at those points. Cylinder G carries the counterpart or maiden b3, in conjunction with which the cutting-knifeworks, and which maybe of india-rubber or of indiarubber and leather.

f is a bar terminating in trunnions and supported by pieces fixed to cylinder G. This bar carries a number of steel blades, which, when at rest, lie against the cylinder, and which after the cut assume the position shown in the drawings, the bar having been turned by the action of a cam, f2, on a roller mounted on a crank-arm,f3, with which it is provided at one extremity. The cylinder H carries a bar, c, on which is iixed a steel blade. The cylinder G carries a bar, d, on which is also iixed a steel blade. The bars c and d are supported by pieces fixed to the cylinders and in which they can turn, and are actuated by cams d2 coming in contact with rollers mounted on crank-arms d3, fitted to the extremities of the bars.

In the cylinder G grooves are formed to IOO receive threads or cords which pass round roller g, as shown in dotted lines.

The paper which descends between the two cylinders G and Il is cut by the knife a almost entirely across, leaving, however, certain parts or shreds,'corresponding to the threads passing round cylinder G', still connecting the descending sheet to the preceding one. Atthis moment, under the action of the cam f2, the bar f is moved to the position shown in the drawings, and thus tears off these shreds an d entirely separates the two sheets and forces the forward end of the descending sheet over the plate ill., which prevents it falling upon the tapes. ll'hen the blades mounted on bars c and d come in contact, the blade e, which projects from cylinder H', folds the sheet of paper and forces its edge between the blade (l and the edge of the recess in cylinder i. The blade (Z by the action of the cam d2 on its bar is caused to bear against the edge of the recess iu cylinder G', against which it nips the paper, and the continued rotation of Y the cylinders carries the sheet forward folded by the cylinder G, the part which had descended over the plate M being drawn back and placing itself against the other part. The sheet being subsequently released by the arm (Z2 of the blade d passing by the end of cam d2, it is detached from cylinder G by the threads and passes between tapes k and L, which carry it to the rollers for the second fold.

rlhe drawings show a machine arranged for making two folds only; but it can, if required, be arranged to .make three, four, or a greater number.

The ink supplied by the ink-ducts L and M L2 and U2 is transferred by rollers to the cylinders N and Q N2 and Q2, on which it is distributed by other rollers, the rollers XV then laying it very evenly on the printing-cylinders.

Fig. 2, Sheet l, is a section of the machine on line l 2 of Fig. l, same sheet. This ligure shows that the machine is donble--that is to say, that a circular cutter, gi, divides the sheets in two, one set of sheets receiving the second fold by the blade T2 forcing them between the rollers R', and the other set receiving the second fold b v the blade T2 forcing them between rollers R2.

The blades are of steel and are supported by pivoted levers T T4. They are actuated by circular cccentrics or by cams and force the folded sheet between the rollers placed beneath them. After the second fold the sheets are delivered'onto a table by a flier or oscillating plate, U, as shown in the drawings, unless it is required to give them more folds.

The delivery of the sheets is shown more clearly on Sheet 3. The sheets carried to roller A are released by a portion of the tapes which conveyed them there and which pass around the rollers l5 and C. The end tapes, or those at each edge of the paper, (indicated by dotted lines in l1`ig.4, after proceeding with the sheets to the table, pass over pulleys E and F and return tol their starting-point. These tapes are shown in dotted lines in Fig. 4 and in Fig. 5 (which is a plan on line 5 (5) by the lines l .l K L. lVhen the sheet comes in contact with the table, the 1l ier or oscillating plate, actuated by an eccentric, bears against such sheet and causes it to leave the end tapes, from between which it is pushed by the motion of said iiier, and to enter the recel vin gbox or tray. rlhe block N,placed in the box or tray, serves to support the packet of sheets received, and it recedes as the packet increases. lVhen the llier or oscillating plate recedes, the last sheet received, which has a tendency to move back again, is arrested by angle-pieces O and l?, fixed at each side of the boxY or tray, and which prevent it bearing against the tapes. The curved part Q of the receiving -table also serves to retain the packet of sheets and prevent it moving back again.

The machine illustrated in Sheets l and 2 delivers two copies of a publication at the same time, the two copies each containing two sheet-s superposed and folded. If the machine is not required to effect such a large output, reels of half the width may be employed, the printing and cutting cylinders being half the length, and for each revolution of the machine only one copy, consisting of two sheets superposed and folded, will be delivered, the slitting-knives being in this case dispensed with.

In the case where the sheets cutl from the webs coming from the reels V and V2 are not required to be superposed the web from reel V is iirst passed over rollerf, then slit longitudinally by knife gi", and next cut transversely and folded by the cylinders G H', after which it is directed by cylinder l over one end of the rollers R R2. The web from reel V 2 is rst passed over roller m, then slit longitudinally by a knife similar to 9*, and next cut transversely and folded by the cylinders G2 and H2, after which it is directed by cylinder G2 over the other end of the rolt ers R R2, the same as in the case of web from reel V', above described. The adjacent ends ofthe two blades T2 T2, which lie, respectively, over one end of the rollers R R2, give the second fold to the sheets coming from the reel V and force them between said rollers, and the other adjacent ends of said blades give the second fold to the sheets coming from the reel V2 and force them between the rollers near their outer endsin the same manner.

Y is the driving-shaft of the machin e, and carries fast and loose pulleys .e and two gear- .wheels, (L c. i The wheel ay gears with wheel b, which actuates all the machine on the side of the reel V', and wheel a gears with wheel b', which actnates all the machine on the side of the reel V2 through suitable intermeshing gear-wheels at the ends of the several rollers, as will be readily understood.

The wheels a and a have hubs or bosses IOO l'IO

keyed to the shafts, and such hubs or bosses can be made independent of their toothed rimsby means of a coupling device. Consequently, by this arrangement, in order to stop the action ofthe entire machine all that is requisite is to shift the drivingestrap from the fast to the loose pulley. To stop one of the two parts or halves of the machine (either that correspond ing with reel V or that corresponding with reel V2) while the other part shall continue in operation, it suliices to shift the coupling device either of the wheel a or of the wheel a. The dri\fingshaft Y will continue to revolve; but the hub or boss of the wheel which is nncoupled will revolve in its toothed rim wit-hout carrying the latter with it, and consequently without driving the part of the machine which it governs. Fig. 2, Sheet l, shows one of said wheels, d, having a hub, c?, keyed to the shaft Y and provided with notches (13 in its circumference. The toothed rim of said wheel has one or more notches, ai, on its inner face, and when said notches register and the plug a5 is inserted the rim and hub are locked. together.

It will thus be seen that this machine will, iirst, print sheets coming from two reels of paper, superpose, fold, and deliver them; second, print sheets coming from two reels of paper and fold and deliver same separately; third, print from one reel of paper only by causing one side of the machine only to be operated. lVhen the two parts of the machine are in operation, either part or half can be arrested without stopping the other part or half.

In the ease where it is desired either to only make use of one reel of paper orto always superpose t-he sheets coming from the two reels it will then only be necessary to have one pair of cutting and folding cylinders, G H,

instead of two. The sheets coming from reels V and V2 will be superposed and pass thus between G and H, which will then cut and fold them, as hereinbefore described. The rollers R Ri2 will be only half as long and there will only be one point of delivery.

In Fig. 7 l have illustrated a. new arrangement of the counterpart or maiden in conjunction with which the cutting-knife works. In this arrangement the leather. At, which is brought to bear upon the cylinder carrying the knife, instead of being' xed on wood, as is often the case, is 'fixed above a strip of india-rubber, Bwhich gives a certain amount of elasticity to the pressure on the knife-cylinder and thus facilitates the cutting. The india-rubberand the leather are mounted in a slot having an inclined side, as indicated in the drawings, and a bar, 0*, which is clamped against them, keeps the whole in position. I may use a counterpart of all leather; but the strip of india rubber placed beneath the leather will produce better results.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination of two rotary printingmachines forprinting from separate continuous webs of paper, the two machines being arranged symmetrically and each having the impressioncylinders, the printing-eylinders and the inkingcylinders arranged in the same vertical line at opposite ends of the combined machine, the cutting and folding' cylinders of each. Ybeing arranged in a horizontal line toward the center of such combined machine, whereby the paper from one reel after being printed by the printing-cylinders at one end of the machine can be led to either pair of cutting and folding cylinders, so thatthe webs of paper after being' printed may either be separately cut into sheets of the same dimensions and then separately folded and delivered or be superposed, cut, and folded together without any change in the direction of the travel of either web,

substantially as described.

2. The combination,with one of the cutting and folding cylinders, of a movable bar journaled in said cylinder and located close to and iirthe rear of the cutting apparatus in the direction of rotation of such cylinder, blades carried by said bar, and cams for pro jecting said blades from the cylinder after the cut is effected to complete the separation of the sheets, and at the same time to direct the forward end of such sheets away from the cylinder which effects the fold, substantially as set forth.

3. In a prin tin g-machine provided with two setsV of printing, cutting, folding, and delivering appliances, a shaft provided wit-h two gear-wheels, each capable of being made fast. with or to revolve loose upon such shaft, one of such wheels serving to transmit motion to one half of the machine and the other wheel to the other half thereof, in combination with IOO fast and loose pulleys on said shaft and a driving-belt adapted to be 'shifted from one -to the other, substantially as described.

A. In a delivery apparatus, the combination, with a set of tapes, the middle tapes of which proceed only to a point above the delivery-table clear of the flier, while the end tapes pass down below the table, whereby the sheet is arrested by coming in contact with the table, of the oscillating iiier and the angie-pieces O P in advance of the plane of the falling sheet, the whole arranged for operation substantially as described.

5. The herein-described cutting apparatus, comprising a cutting-cylinder, a knife carried by said cylinder, a maiden, a stripof indiarubber thereon, a working-surface of leather over said india-rubber strip, and a bar removably securing said leather in position, so as to oppose a yielding elastic pressure to the action of the knife, substantially as described.
